Shouzou and Ine, an old married couple, are known to everyone as a pair of lovebirds. One day, they wake up to find they look like their younger selves! When Mino, their granddaughter, sees them, she's shocked by their transformation, and she's not alone!
If I can stay with Grandpa, 
then anything is fine with me.
لا بأس بأيّ شيء في نظري
.ما دمت سأكون مع زوجي
Solang ich bei meinem Mann bleiben kann,
is mir alles andere allerlei.
L'importante è che possa restare
accanto al nonno, il resto non conta.
Desde que eu possa ficar ao lado
do meu marido, qualquer coisa serve.
Везде будет хорошо,
лишь бы рядом с мужем.
